-- iOS 8.

 ## Installation
 
 ### CocoaPods
 
+TUSafariActivity is available through [CocoaPods](http://cocoapods.org). To install
+it, simply add the following line to your Podfile:
+
     pod 'TUSafariActivity', '~> 1.0'
+
 ## Usage
 
 *(See example Xcode project)*
 
 Simply `alloc`/`init` an instance of `TUSafariActivity` and pass that object into the applicationActivities array when creating a `UIActivityViewController`.
 
+### Objective-C
+
 ```objectivec
 NSURL *URL = [NSURL URLWithString:@"http://google.com"];
 TUSafariActivity *activity = [[TUSafariActivity alloc] init];
 UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:@[URL] applicationActivities:@[activity]];
 ```
 
+### Swift
+
+```swift
+let URL = NSURL(string: "http://google.com")!
+let activity = TUSafariActivity()
+let activityViewController = UIActivityViewController(activityItems: [URL], applicationActivities: [activity])
+```
+
 Note that you can include the activity in any `UIActivityViewController` and it will only be shown to the user if there is a URL in the activity items.
